We have developed an approach for modelling a coupled system of many subwavelength halide perovskite resonators. Their highly dispersive material parameters makes this a challenging problem, but, given their rapidly growing usage in electromagnetic devices, efficient mathematical methods like ours are becoming increasingly valuable. Our method is sufficiently concise that we have been able to use it for an inverse design problem, which would have required significant computational effort to solve using numerical simulation methods. These results can accelerate the design of advanced photonic devices [1]}, [2]}, including those with complicated structures and geometries, such as the biomimetic eye developed by [3]}.
